Fix VLYNQ device enable for DG834Gv1
This patch allows VLYNQ devices on the DG834Gv1 to be successfully enabled. Currently the "__vlynq_enable_device" function attempts to set the VLYNQ device clock divisor to values from 1 through 8 until a link is successfully established. On the DG834Gv1 (but not the DG834Gv2), setting the VLYNQ device clock divisor to 1 (full rate) results in all further VLYNQ operations failing (including software reset), so the device is never enabled. This patches changes the function to only attempt divisors 2 through 8, and hence the device is successfully enabled.
